Summary

CATALYST TR-T9 is designed primarily for use in flexible urethane (polyurethane) applications. It is widely regarded as a benchmark catalyst for producing flexible polyether urethane foams, thanks to its high catalytic activity in promoting the isocyanate–hydroxyl reaction (urethane formation).

Applications

  • TR‑T9 (a tin catalyst, stannous octoate) is designed for use in flexible urethane foam applications: it is a clear, low‑viscosity fluid which dissolves well in polyether polyols and many organic solvents.
  • It acts as a “benchmark” catalyst in the production of flexible polyether urethane foams, because of its strong performance in promoting the isocyanate‑hydroxyl (urethane‑forming) reaction.
  • Typical usage: high‑speed, high‑volume foam production, providing high gel catalyst activity and uniform flexible foam quality.
